Product Description

Density / Specific Gravity Meter <DA-650/DA-645/DA-640>

Summary of Test Method
A small volume (approximately 1 to 2 mL) of liquid sample is introduced into an oscillating sample tube and the change in oscillating frequency caused by the change in the mass of the tube is used in conjunction with calibration data to determine the density, relative density, or API Gravity of the sample. Both manual and automated injection techniques are described.

Easy to check measurement cell
No air bubbles, no contamination
Equipped with sampling and dry pump

Applications:

Beverages, foods, petroleum, pharmaceutical, alcoholic beverages, etc.
